Alcohol Screening

There are different methods to go about performing alcohol screening. Alcohol can be found in a person through various different tests. There are a few types of alcohol screening test kits available. This would include the urine, saliva, and even blood tests. As well, the breath tests (breath analyzers) are probably the most popular way of screening a sample for alcohol. Each one holds some benefits over the other and one may be better than the other for certain situations.

Blood Tests
Blood tests will look at how far impaired you are from consuming alcohol. What is observed is your blood alcohol concentration level. There is a link between your blood and your impaired level and with blood tests, you can find out how impaired someone is. Blood tests are the best alcohol screening method if accuracy is the most important factor.
Urine Tests

This is another way to perform alcohol screening. However, there are problems with urine tests. A urine test can tell you if someone has consumed any alcohol. Sadly, a urine test cannot actually identify how impaired the person is. Two hours after the alcohol is drunk, it will show up in the urine. There are also problems with false positives occurring on urine tests for alcohol.

Saliva Tests
Saliva tests also work for alcohol screening. The problem is that there is no proof to date that there is a guaranteed link between blood alcohol concentration level and the concentration level of alcohol in your saliva. Saliva tests are still in development for alcohol as everything is not figured out yet. Saliva tests can work well for alcohol screening if the goal is to get a rough idea on how impaired they are but for an exact level, it is not the best resource for alcohol screening.
